ABSTRACT

Aspects of the disclosure relate to inspecting a data stream. Some aspects include conveying the data stream through a multi-level data channel and inspection architecture. The architecture includes a multi-level data pipeline. The pipeline includes a plurality of parallel pipes. The output of one pipe provides an input to a successive one of the pipes. The method further includes receiving the data stream at an upstream portion of the pipeline and inspecting data in the data stream for converting the data stream into inspected data. The method then outputs inspected data at a downstream portion of the pipeline. Each of the pipes inspect the data on a different level of data channel inspection than the other pipes. Each level of data channel inspection has data attributes and/or metadata extracting capabilities. Each pipe transfer data packets at greater than or equal to a threshold data transfer rate.

FIELD OF TECHNOLOGY

Aspects of the disclosure relate to data architectures. Specifically, aspects of the disclosure relate to architectures for use in verifying and authenticating data in data streams.

BACKGROUND OF THE DISCLOSURE

Digital packet inspection (sometimes referred to as deep packet inspection) (“DPI”) inspects in detail the data being sent over a computer network. At times, DPI can take actions, with respect to the data, such as blocking, re-routing, or logging the data. DPI is often used to insure that the data is, inter alia, in correct format, to check for malicious code, eavesdropping and for internet censorship.

Many DPI methods, however, are slow and bandwidth-consumptive. This limits their effectiveness—especially for use with high-bandwidth applications. It would be desirable to develop more efficient methods of DPI.

While special routers are being developed to perform DPI, it would also be desirable to develop architectures that are directed to increasing speed and performance of DPI. It would be yet further desirable to increase speed and performance of DPI, yet, at the same time reduce the bandwidth consumption by DPI.

SUMMARY OF THE DISCLOSURE

A multi-level data channel and inspection architecture is provided. In certain embodiments, the architecture may include a multi-level data pipeline. The pipeline may receive a data stream at an upstream portion of the pipeline and output inspected data at a downstream portion of the pipeline.

The pipeline may include a plurality of pipes. Each of the pipes may include one or more of a group of mechanisms. The mechanisms may include a data manager, a data ingestor, a data collector, a data processor, a data extractor, a data attribute updater, a query selector, and a visualizer. The data manager is preferably configured to coordinate passage of the data into and out of the pipeline. The data manager may also coordinate the passage of the data between one or more of the group of mechanisms within each pipe.

Each of the plurality of pipes may be configured to inspect the data on a different level of data channel inspection than any of the other of the plurality of pipes. Each level of data channel inspection may have an individual data attribute and/or metadata extracting capabilities. Each of the plurality of pipes may be arranged in a serial connection with the other of the plurality of pipes such that an output of one pipe provides an input to a successive one of the plurality of pipes.

DETAILED DESCRIPTION OF THE DISCLOSURE

Aspects of the disclosure relate to architectures and methods associated therewith according to certain embodiments. Preferably present structures for intercepting the data and/or hiding/altering the contents of the data. The architectures set forth herein enables intercepting the data and/or hiding/altering the contents of the data because the analysis and review of the data is preferably performed by the architectures either prior to loading of the data into the greater system and/or at certain selected, preferably pre-determined, points of the data channel.

Theoretically, the architectures of the current embodiments can preferably be conceived of as a horizontal review system. Such a review system may preferably be configured to process data streams, data objects, and/or data sets (collectively referred to herein as, the “data”). Each of the above preferably have multiple parts, varying content and different data types. Accordingly, the architectures fill a need to create a tiered inspection layer that allows data to be inspected, not just as a packet level but in varying gradations—i.e., varying levels of inspection. Creating this multi-level data “filter” architecture preferably enables the data to be searched in various gradations of searching. In addition, such an architecture passes the data through different quality assurance parameters. Checking the data with respect to such parameters informs analysis and review (“A&R”) of the data along with certifying the data vis-à-vis other functional workflows.

The embodiments of the architecture disclosed herein involve comprehensive A&R channeling across one or more digital pipes.

A basic channel could include the following—

Data Packets (DP1, DP2, . . . DPn)−x.

Each of data pipes (L1, L2, . . . Ln) may include complementing pairs. The Data pipes can be segmented into levels each having specific/varying data attribute/metadata extracting capability. For the purposes of the disclosure herein, L1, a first data pipe, should be considered a basic data audit trail. Each new layer—i.e., L2-Ln—may preferably add a new set of policies and requirements.

Relatively large amounts of real-time, or streaming, data requires one or more data processing pipelines. Each pipeline preferably contains paired pipe layers, the advantages of which will be described below in more detail.

A multi-level data channel and inspection architecture is provided. The architecture may include a multi-level data pipeline. In certain embodiments, the pipeline may be configured to receive a data stream. The data stream may be formed from a plurality of data packets.

At an upstream portion of the pipeline, the pipeline may be configured to receive the data stream. At a downstream portion of the pipeline, the pipeline may be configured to output inspected data.

The pipeline may include a plurality of pipes. Each of the pipes may include one or more of a group of mechanisms including a data manager, a data ingestor, a data collector, a data processor, a data extractor, a data attribute updater, a query selector, and a visualizer, and/or any other suitable mechanisms.

In some embodiments, the data manager may be configured to coordinate passage of the data into and out of the pipeline, and between one or more of the group of mechanisms.

Each of the plurality of pipes are coupled in parallel to one another within the multi-level data pipeline. In such an arrangement, an output of each of the plurality of pipes is coupled to an input received from the data stream.

Also, in such an arrangement, an output of each of the plurality of pipes is coupled to provide input to the inspected data exiting the tunnel.

In some embodiments, a first of the plurality of pipes may be configured to transfer only data packets having a first data packet size. The first data packet size may be a size that is equal to or greater than a first threshold size. In such embodiments, a second of the plurality of pipes may be configured to transfer only data packets that have less than the first data packet size. In certain embodiments, the second data pipe may be configured to transfer data packets that have greater than or equal to a second threshold size.

Some embodiments may include a plurality of pipes which may be configured to transfer data packets at greater than or equal to a threshold data transfer rate.

Each of the plurality of pipes may be configured to transfer data packets at less than or equal to a threshold data transfer rate. It should be noted that in such an embodiment, the data packets may have been diverted from a main data stream. The data packets may have been diverted from the main data stream at least because the data packets have been selected for inspection and analysis. The transfer rate of the diverted data packets may need to be slowed for inspection and analysis. Accordingly, the data packets, when travelling in the main data stream, may be flowing at a first data transfer rate. The same data packets, when travelling in the diverted data stream, may be slowed to no greater than a second data transfer rate—where the second data transfer rate is slower than the first data transfer rate.

In certain embodiments, each of the plurality of pipes may be configured to transfer data packets at a data transfer rate that is different from the data transfer rate of the remainder of the plurality of pipes. In some embodiments, each of the plurality of pipes may be configured to transfer data packets at a data transfer rate that is different from the data transfer rate of some of the remainder of the plurality of pipes but the same as, or similar to, the data transfer rate of another portion of the remainder of the plurality of pipes.

In certain embodiments, the plurality of pipes may be configured to transfer data packets a level of data security that is different from the level of data security of the remainder of the plurality of pipes.

Apparatus and methods described herein are illustrative. Apparatus and methods in accordance with this disclosure will now be described in connection with the figures, which form a part hereof. The figures show illustrative features of apparatus and method steps in accordance with the principles of this disclosure. It is understood that other embodiments may be utilized, and that structural, functional, and procedural modifications may be made without departing from the scope and spirit of the present disclosure.

Conventional data inspections are “vertical” in nature—i.e., data is reviewed and analyzed in such inspections, but no mechanism for intercepting and hiding/altering the data is provided. The following embodiments provide modules and mechanisms for intercepting data and providing necessary review mechanisms for data removal, adjustment and alteration.

FIG. 1 shows a group of possible audit mechanisms for use along a data pipe 100. Data pipe 100, may also be referred to herein as a data tunnel. This group of possible audit mechanisms may include data ingestor 102, data collector 104, etc. each of these mechanisms may be used alone or in some combination with one another. It should be noted that the channel data manager (not shown in FIG. 1) may coordinate passage of the data into, between and out of one or more of the mechanisms.

Data ingestor 102 may serve to bring the data stream 101 into the pipeline. As such, data ingestor 102 preferably is on the externally-facing input side of the data pipeline. It should be noted that each individual pipe in which some or all of mechanisms 101-118 are arranged preferably have different set of requirements regarding data integrity and verity that can be implemented as part of an initial application. These sets of requirements may also support real-time adjustment of data based on real/perceived threats and/or errors in the data.

It should be noted that each of multiple pipes may be arranged with various audit levels. The channel data manager may force or bypass one or more of input 101, output 118, and mechanisms 102-116, or certain levels within mechanisms 102-116, based on initial and/or subsequent reviews. Such forcing or bypassing may be dependent, in certain embodiments, upon the data attributes/metadata-extracting capability of the individual pipes.

The data collector 104 may preferably coordinates transportation of data from ingestion layer to, and, at times, throughout, the rest of data pipeline.

The data processor 106 preferably processes the collected data from the previous layer. The data processor 106 may route the data to a different destination—the different destination being one that is either in or out of the pipe—and/or classify the data flow. It should be noted that architectures, according to the embodiments, can preferably identify packet flows, rather than conducting a packet-by-packet analysis. This enables institution of control actions based on accumulated flow information.

Data extractor 108 may extract data based on data patterns. These patterns enable extractor 108 to mine arbitrary information and extract certain, selected information, from the data which is received and reviewed.

Data attribute updater 110 preferably is configured to add custom properties to data. Such custom properties may include data extracted from primary and secondary data sources to add/remove/edit clarity, value, security or other data attributes. An example could include adding data markers as each packet, or other segment, of data is inspected. Another example could include adding one or additional layers of tokenization. The additional layers of tokenization may depend on the sensitivity of the data passing through the architecture as well as the availability of custom fields required for certain documents and/or certain classes of documents.

Data query selector 112 provides a layer wherein strong inspection and review processing takes place. Such inspection and review processing may include, for example, validating data extracted via extractor 108 and validating such data against certain policies to meet regulatory, or other relevant, needs.

Data visualizer 114 may be a layer that provides full business infographics, as necessary, to express the static and dynamic results obtained from the ongoing analysis and review (“A & R”).

Data auditor 116 may preferably audit data. In addition, data auditor 116 may provide a supervisory layer for continuously, or periodically, monitoring traced data. Data auditor 116 may preferably output the data as inspected data 118.

FIG. 2A shows a multi-level data pipeline 200. Multi-level data pipeline 200 preferably includes an incoming data stream 202. Data stream 202 is preferably a candidate for A & R.

Each of pipes 208-218 preferably may include one, some or all of mechanisms 102-114 shown in FIG. 1. In such a pipeline, the coordination of movement of data from one pipe to the next may also require an additional, overseeing data pipeline manager (not shown) that coordinates passage of the data into, between and out of one or more of the pipes 208-218.

It should be noted that the arrangement of pipes 208-218 may be in one of a number of various arrangements. For example, the pipes may be laid out in a serial arrangement—i.e., the output of a first pipe may provide the input for a next pipe and so on. FIG. 2B shows the pipes laid out in serial arrangement 240.

In another arrangement, pipes may be laid out in a parallel arrangement—i.e., all (or some) of the pipes may have inputs that receive different streams and outputs that output different streams. FIG. 2C shows this network architecture. This network architecture, which includes a multi-level data pipeline, shows the various pipes disposed in a parallel fashion 280 in accordance with principles of the disclosure. It should be noted that the decision as to which data goes into which pipe may be handled by, for example, a data pipeline manager (not shown in FIGS. 2A-2C). Such a data pipeline manager may preferably determine based on a suitable algorithm which the address for transmission of the data packets. This target address may depend on, for example, packet size, packet security, or any other suitable factor.

In some parallel embodiments, multi-pipe, or multi-tier, data diverters may be implemented. These diverters may serve to reduce bandwidth consumption relating to in-line data review. Each pipe, or tier, may correspond to a security level associated with data packets found in a data stream. For example, a top-level pipe, or tier, may be reserved for reviewing a data stream including data packets that include, or reference, a social security number. A second exemplary pipe or tier may be reserved for reviewing a data stream including data packets that include, or reference, an account number. The security-based arrangement of pipes may also be utilized in accordance with certain embodiments of the serial-based arrangement of the pipes.

In some embodiments, each pipe, or tier, may correspond to a size-dimension associated with data packets found in a data stream. For example, a top-level pipe, or tier, may be reserved for reviewing a data stream including data packets that less than a pre-determined size threshold. In such a pipe or tier, the speed can remain relatively high because the packets are small and can be inspected relatively quickly. A second exemplary pipe or tier may be reserved for reviewing a data stream including data packets that are greater in size than the first threshold but less than a second threshold, etc. The security-based arrangement of pipes may also be utilized in according with certain embodiments of the serial-based arrangement of the pipes.

FIG. 2D shows still another illustrative network architecture include a multi-level data pipeline, with various pipes disposed in a parallel fashion, having a front end logic block(s) 205 and/or a back end logic block(s), in accordance with principles of the disclosure.

Logic block 205 preferably serves to parse data stream 202. As described above, logic block may divide data stream into various streams, each including a portion of the data stream 202. Each of such portions may include a portion of the total data stream.

FIG. 2E shows, schematically, logic block 205 parsing data stream 202 into pre-determined packets. Each of the packets, depending upon its characterization, may be transferred through one of pipes 208, 210, 212, 214, 216 and/or 218. Such parsing may include dividing data stream 202 based on the size of packets. As such—all packets having a first packet size, or within a first packet size window, may preferably be transmitted through pipe 208; all packets having a second packet size, or within a second packet size window, may preferably be transmitted through pipe 210.

It should be noted that the relative speed of transmission of each of the pipes should preferably depend, to some extent if not completely, on the size of the packets.

In other embodiments, such parsing may include dividing data stream 202 based on the contents of packets. For example—all packets having a high-security payload, such as a social security number, may preferably be transmitted through pipe 208; all packets having a second security level payload, such as an account number, may preferably be transmitted through pipe 210.

In some embodiments, there may be multiple data pipeline managers that are disposed throughout various pipes 208-218. For example, one data pipeline manager may be assigned to coordinate the movement between pipes 208-212 while another may be assigned to coordinate the movement between pipes 214-218. Alternatively, there may be more data pipeline managers, as needed for the system.

The data stream 202, formed from packets 1 to N at 204, preferably exits as inspected data 220, formed from inspected packets 1 to N at 222.

As described above, data packets (DP1, DP2, . . . DPn) may form a data stream 202. Data stream 202—may be parsed into components. The parsing may break down each data stream 202 into component streams of different packet size.

For example a data stream: DS may be broken down into component data streams DS₁, DS₂, DS₃ . . . DS_(n). The data streams DS₁, DS₂, DS₃ . . . DS_(n) may each correspond to a different packet size. DS₁, DS₂, DS₃ . . . DS_(n) may correspond to packet size (“PS”) PS₁, PS₂, PS₃ . . . PS_(n).

Further, each PS may preferably be routed to a unique data pipe. As described above, data pipes (L₁, L₂, L₃ . . . L_(n)) may each correspond to a specific packet size (PS₁, PS₂, PS₃ . . . PS_(n)). As such, the size and characteristics each of the data pipe may be customized. The data pipe may be customized based on the type of data packet, and, consequently, the characterization of the partial data stream, that it carries.

As shown in FIG. 2F, each of data pipes 221, 224, 226 and 228 may preferably be configured to carry different packet sizes. Moreover, each of data pipes 221-228 may be configured to have different processing capacities, as signified by the different relative sizes of data pipes 221-228 shown in FIG. 2F. Accordingly, each of data pipes 221-228 may be of different actual sizes.

In addition, the speed of processing of each of the data pipes may be different. As shown in FIG. 2G, each of data pipes 232-238 may preferably present—i.e., transfer information—at different transmission speeds. In some embodiments, the smaller packets may be identified by logic block 205, analyzed and reviewed, and then transmitted at a faster rate, while larger packets may be identified, analyzed and reviewed, and then transmitted at a slower rate. Exemplary rates of 100 gigabytes (“GB”)/second, 50 GB/second etc. are shown in FIG. 2G but any suitable rates may be used in the embodiments. It should be noted that in certain embodiments, all of the pipes may preferably transmit information at a similar rate.

FIG. 3 shows a schematic diagram of an exemplary data review tunnel 300 according to certain embodiments. Data review tunnel 300 preferably includes, and communicates with, data review decision rules module 302, data interpreter module 304, data collector module 306 and/or data reporter module 308. The entirety of the data review, and data movement, and records movement, attendant thereto, is preferably coordinated by data review tunnel manager 310.

The data review decision rules module 302 preferably includes rules for reviewing and analyzing the data. Data review tunnel manager 310 preferably communicates with data review decision rules module 302 to determine the meets and bounds of the analysis and review of data that will take place.

Data collector module 306 preferably is configured to receive, review and analyze data received by data review tunnel manager 310.

Data interpreter module 304 is preferably configured to review data received by data review tunnel manager 310 and to establish the type of data for reference by data review tunnel manager 310. Data reporter module 308 may be configured to prepare a report based on the analysis and review conducted by data review tunnel manager 310 in conjunction with data review decision rules module 302, data interpreter module 304 and data collector module 306.

In certain embodiments, it should be noted that the four “spokes” 302-308, that extend from data review tunnel manager 310, together with data review tunnel manager 310, may form a multiplexer such that any packets that enter spokes 302-308 may require an acceptance by all of spokes 302-308 prior to exiting data review tunnel manager 310. As such, tunnel 300 preferably acts as an AND logic gate which validates, and allows to pass, data packets only after full review and validation at the four different spokes 302-308.

FIG. 4 shows a schematic diagram of an exemplary arrangement 400 of data review tunnels 416-422 as they intersect with a plurality of complementary pipe pairs 408-412. Data packets 402-406 are shown to the left as entering and traveling through pipe pairs 408-412.

Pipe pairs 408-412 are shown as complementary pairs as opposed to single data pipes. The complementary pairs enable the arrangement 400 to process large amounts of real-time or streaming data.

In certain embodiments, the complementary pairs of pipes 408-412 may illustrate schematic descriptions of double-key systems. For example, when a first entity wants to contact a second entity using electronic communication, the first entity may encrypt the transmission using a first encryption key. On the receiving end, the second entity, may decode the transmission using the key with which the first entity encoded the information. However, if a malicious actor breaks the encryption key, then the communication is in danger of a security breach.

In order to increase security, the transmitter of information may transmit information over two pipes instead of one. In order to hack such a transmission, a malicious actor will be required to hack both information pipes in order to reconstruct the transmission. If an even greater level of security is desired, then the two-pipe solution can implement two security keys. For example, if the transmitter uses a public key provided by the recipient to encrypt the transmission and then further encrypts the transmission using a the transmitter's own private key, then the recipient will be required to decode the transmission using both the public key and the private key. The security of the transmission will be further heightened by using dual (or more) transmission pipes to transmit the transmission.

Tunnels 416-422 may be configured as data review tunnels 300 set forth in FIG. 3. Tunnels 416-422 are shown as intersecting both complementary pipes of each of pairs 408-412. In such an architecture, tunnels 416-422 can provide the data channeling sufficient for implementing the processing, et al., shown in FIG. 3. Tunnels 416-422 preferably stretch across both pipes because the information in both pipes is preferably critical to performing analysis and review of the information in both pipes.

The data channeling described herein in the portion of the specification corresponding to FIGS. 1-4 may support real-time or near real-time data inspection and review. Furthermore, the data channeling may enable efficient control and data attribute/metadata extraction to compare against data records stored in a System of Record/Registration (“SOR”) and/or Authorized Data Source (“ADS”).

Preferably all of the embodiments shown herein allow for certain data stripping capabilities based on SOR and/or ADS including the ability to compare and/or correct inconsistent data—i.e., data that does not conform to the SOR and/or the ADS.

Moreover, the systems and architectures described herein preferably provide the ability to dynamically freeze one or more data channels with respect to one or more data packets/streams. Freezing a data channel may be required in a data breach situation or other emergency situation. In addition, the systems and architectures described herein preferably allow certain data to pass based on a pending registration/attribute review, or put in a holding pattern and/or holding zone pending the exit of frozen data currently stuck in the channel.

In certain embodiments of the architectures shown in FIG. 1-4, the pipes could have different set of requirements that can be implemented as part of an initial application but also support real-time adjustment based on real/perceived threats or any other selected stimuli.

The steps of methods may be performed in an order other than the order shown and/or described herein. Embodiments may omit steps shown and/or described in connection with illustrative methods. Embodiments may include steps that are neither shown nor described in connection with illustrative methods.
